Answer:
m = {-6, -4}
Step-by-step explanation:
<u><em>Subproblem 1:</em></u>
Set the factor '(6 + m)' equal to zero and attempt to solve:
Simplifying
6 + m = 0
Solving
6 + m = 0
Move all terms containing m to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + m = 0 + -6
Combine like terms: 6 + -6 = 0
0 + m = 0 + -6
m = 0 + -6
Combine like terms: 0 + -6 = -6
m = -6
Simplifying
m = -6
<u><em>Subproblem 2:</em></u>
Set the factor '(4 + m)' equal to zero and attempt to solve:
Simplifying
4 + m = 0
Solving
4 + m = 0
Move all terms containing m to the left, all other terms to the right.
Add '-4' to each side of the equation.
4 + -4 + m = 0 + -4
Combine like terms: 4 + -4 = 0
0 + m = 0 + -4
m = 0 + -4
Combine like terms: 0 + -4 = -4
m = -4
Simplifying
m = -4
Answer:
D) In step 5, he should have multiplied both sides by 1/3
Step-by-step explanation:
Given expression,
Using distributive property,
Using additive property of equality,
Make the fraction with same denominator by taking LCM of Denominators in left side the equation,
Adding fractions,
Write 3 as a fraction,
Using multiplicative property of equality for isolating the variable in right side, multiply 1/3 in both sides,
Hence, it is clear that he did mistake in step 5 he should have multiplied both sides by 1/3.
Its c, the line with an open circle and the red line directed towards the left
Answer:
2/3
Step-by-step explanation:
This question is asking you to simplify the fraction 40/60. You can factor out the number 20 from both:
Now you can cancel 20 from the top (numerator) and the bottom (denominator) and get 2/3 as your final answer.
